Experience : The term “tour de force” must have been invented for practically any performance turned in by Ms. Lowe, whose petite physical stature stands in direct contrast to her giant talent. Her list of credits and awards is as long as your arm. Equally at home interpreting roles written by Edward Albee (“Who’s Afraid of Virginia Woolf ” and “Seascape”), Jean-Paul Sartre (“No Exit”), Henrik Ibsen (“A Doll’s House”), George Bernard Shaw (“Candida”), William Inge (“Picnic”) or Tom Stoppard (“Arcadia”), Ms. Lowe never strikes a false chord. And her recent triumph in “The Belle of Amherst” was a performance for the ages.
